The midpoint of the given line in coordinate form (x, y) is -0.5, 0)
<h3>Midpoint of a line</h3>
The midpoint of a line is the middle of the given line. Given the coordinate points (x1, y1) and (x2, y2), the midpoint of the line is given as:
M(x, y) = {x1+x2/2, y1+y2/2}
Given the coordinate points on the line (-2, 1) and (1, -1)
Substitute the given coordinate points into the formula to have:
M(x, y) = {-2+ 1/2, 1-1/2}
M(x, y) = {-1/2, 0/2}
M(x, y) =(-0.5, 0)
Hence the midpoint of the given line in coordinate form (x, y) is (-0.5, 0)

Answer:
27
Step-by-step explanation:
3 x 9 = 27
you just multiply the two. (if it asks for temperature after the hours just subtract)
Answer:
x = 16 2/3
Step-by-step explanation:
The altitude divides the triangle into similar triangles. We can form the ratio between the hypotenuse and the short leg for two of the triangles. Those ratios will be a proportion:
10/6 = ((x-6) +6)/10
100/6 = x . . . . . multiply by 10 and simplify
x = 16 2/3
Given:
The mean age of 5 people in a room is 26 years.
A person enters the room. The mean age is now 33.
To find:
The age of the person who entered the room.
Solution:
Formula for mean:
The mean age of 5 people in a room is 26 years.
The mean age is now 33. It means, the mean age of 6 people is 33.
Now, the age of the person who entered the room is
Required age = Sum of ages of 6 people - Sum of ages of 5 people
= 
= 
Therefore, the age of the person who entered the room is 68 years.
Answer:
2x²-7x
Step-by-step explanation:
7x²-5x²=2x²
